IMPROVEMENT 'IN APPARATUS FCR DISTILLING.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom lit may concern:

Bc it known that I, J ons M. WEYAND, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and improved Distilling- Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawings forming part ofthlsspecication.

The object of this invention is to facilitate the generating, dephlegmatizing, aromatizing, -and refrigerating of alcoholic vapors, and-to thereby simplify and economize the process of distillation.

The main feature of 'the present invention is-to so constructthe apparatus that steam and mash 'are made to pass-continually in opposite directions through the same compartments, the steam takingnp, and the mash giving o alcohol during such uninterrupted passage. Bythis method the temperatures can be so completely regulated, that spirits of the requisite grade and prooi' can be produced with great cxactness.

The invention consists also in a novel 'construction and arrangement of the generating compartment, in which the mashV is absolutely mingled with steam an broughtin contact with heated surfaces to evaporate all its alcoholic contents;' also, in a new arrangement of combined evaporating and condensing chambers of :tnovel dephlegmatizin g, aromatizing, andreiiigerating or condensing apparatus, all as hereinafter more fully described and specified.

In the accompanying drawings- `Figure 1 represents a vertical longitudinal section of the dephlegmatizing, aromatizing, and refrigerating apparatus.

'Figure-.2 is a vertical longitudinal section ofthe generating and evapbrating apparatus.

Figure 3 is a vertical transverse section of the entire apparatus.

Figure 4 is a' plan view of a mash-chamber.

Figure 5 is a plan view of a chamber foi-'conducting the products of condensation.

Similarletters of reference indicate corresponding parts.

The entire apparatus consists of two series of com-v partments'placed side .by side, the irst series serving to produce the alcoholic vapor, while in the second series the same is purified, aromatizcd, and condensed.

The first series' consists of six or more compart ments A, B, Q, D, E, and F,- which are placed one above the other, as in figs. 2 and-3, in form of wedgeshaped boxes with inclined bottoms, as shown.

The mash enters a pipe, a, in the upper compartment F, and is in that 'pipe carried from-end to end of suchvcompartment F, thence through the comparte ments E and-D, successively. 'Ihe pipe al is coiled' or bent in the three aibresaid compartments to have its length increased, and to expose the 'mash thereforeto the heat in the said compartments, so that the alcoholic contents `of the mash may be ready to evaporate'- as soon as the mash leaves the pipe a.

The pipe a discharges the mash into the higher end of an inclined box, G, which is placed into the compartmcnt O.

On the bottom of this box is set up a series of projecting flanges b, as in g. 4,- which det-ains the mash as it slowly. flows toward the lower end of the box to allow its alcoholic contents to evaporate.

A pipe, c,conducts the mash from the lower end of the box G, into the upper end ot a similar box, H, l

which is arranged in the compartment B, and whichis also inclined and provided with dctaining flanges, as sliown. f

The box H is provided with a cover, d, which prevents the products 'of condensation from dropping into the box. A pipe, c, conducts the mash, which by this time is almost entirely spent, fi. c., dealcholized into a drum or pot, I, that is suspended from the bottom j' of the compartment B into the narrow end of the comparb ment' A. A

From the b ottom of the drum I projects into the same apipe, g, which is open at both ends, and ifthe upper end of which the mash must rise in the drum before it can ilow out through such pipe g into the same almost entirely before it can escape through an S-shaped pipe, j, and is, while in the compartment, exposed not only to the heated surfaces of steam pipes It, which pass through A, but also to actual contact with the steam, and agitated by the same, so that it l will give off all the alcoholic contents that may have remained in it. The mash is so thoroughly heated, not only in the pipe a and boxes G H, but also in the compartmentA that its alcohol, which evaporates 'much quicker than water, must be al1 evaporated and separ-Y ated betore the mash is allowed to escape.

The vapors thus produced, i. e., the mixture of steam and evaporated alcohol, enter the tub I through a pipe,

Z, which conducts them to the bottom of said tub, so. that they willhave to pass entirely through the mash l therein, and absorb the alcohol contained therein.

The vapors now ascend in the compartment B, pass` through au aperture, 1min the cover of B and O, thence into D and E successively, they always traversing the entire lengthofeach 4compartment before leaving the same. As they ascend, the vapors gradually cool and give oli' their heat to ,the mash, which becomes graduallywa-rmer as it descends. As the vapors ascend, they come iu contact with the cooler top plates of the several compartments, and some of their aqueous contents are thereby condensed. These products of condensation drop down from the said covering plates and fall upon the inclined bottoms of the compartmentson which theyflow down.

'from passing through the saine.

As the products of condensation arrive in the lower part` ofthe compartment'B, .they are carried off by a pipe, o.

The temperatures in the several compartments can be so regulated that noxious contents of the vapors will becondensed with the water before the vapors leave the compartment E.

Under the boxGis arranged a steam-box, J, through which steam is constantly passed for the purpose of evaporating as much as. possible the contents of the mash that pass through the same. The vapors-thus produced from the mash become mixed with those ascendingfrom the compartment A, and become partly purified before they leave thecompartment E.

The vapors pass from the compartmet E in a short straight pipe, p, through the compartment Fwith the contents of which they are not broughtiu contact, and ale then, by a pipe, r, carried to the second series of compartments in the dephlegmator.

The dephlegmator consists of two or more metal casesL L', of oval cross-section, set inclined into boxes -M M', which receive cold water at the lower cud through A a pipe, f'.

As the vapors enter the cases L thus cooled, their aqueous cntents will condense and will flow on the inclined bottoms of such cases and through the pipe s connecting the same, while the vapors pass on above the phlegm.

"'lhe latter is,from the lower case L', carried back to the vessel C in pipes t t, and becomes there mixed with `the products of condensation previously mentioned.

`The alcoholic vapors pass .from the lower case L' through a pipe, u, into the aromatizer N, which is a slightly inclined cylinder, containingr perforated shelvs c lv, upon which the` fragrant ingredients to be used are placed. v

The cylinder N is surrounded by an annular steamchamber, O, which receives steam through a pipe, u, and discharges it through a pipe, 'The heat of the steam causes the ingredients on the sleeves to give-oil' their ethereal oils, which are absorbed by the alcoholic vapors passing through the cylinder N. The water from thel dephlegniator is vcarried by a pipe, b', into the chamber F. h

The vapors are thus aromatized. They pass from the cylinder N through a` pipe, y, into the refrigerator P.- The same is an inclined metal case surrounded by a water-chamber, R.

maar

. Water is carried to it in a pipe, z, at the lower end, and gradually ascends as it gets warmer, until it is finally discharged into the case F by a pipe, a. The vapors passing through the cold chamber P will be `condensed, and can be drawn off through a pipe, c'.

pipe a will, in such chamber, be entirely' surrounded by the' same. The mashas it enters the apparatus will therefore berst warmed by this water, and then in the lower compartments by theascending vapors. The water escapes from the compartment F through an annular pipe, d', which surrounds the -upper part of the pipea, as shown.

The cases L L' should have openings at the endsto facilitate the cleaning of the' vapor passages. In case the. aromatizer is not required, theA refrigerator is' directly1 connected withthe dephlegmator.

It is evident that the number of cases in the first series of compartments may be varied at will in accoi-dance with the size of' apparatus used, and amount of liquid to be distilled. The several compartments may be secured in a suitable frame-work, S, and connected by bolts e', or otherwise, in suitable manner.

Having thus described my invention.

I claim as new and desire to secure 1. rlhe chamber A containing the heating surfaces It, the steam-pipe h, and perforated false bottom/i to disturb and agitate the mash and evaporate its alcoholic contents, as set forth.

2. The drum I, receiving the mash and steam, the latter near the bottom, so that it will agitate the mash, as set forth.

3. The mash-evaporajtiug pau G, combined withthe 7. The. aroniatizer N containing the 'perforated shelves 'u lv, and arranged within the annular steamchamber O, substantially as hereint shown and described to operate as set forth.-

8. The refrigerator P, arranged within the inclined" cold-water chamber It, and connected with the aromatizer or dephlegmator, substantially as herein shown and described. y l

9. The herein described combination with each other of the several compartments A B OD E F, d'ephlegmator L L', and refrigerator P, all arrangedto operate as set forth.
